Does the Rexing M3 record front, rear, and cabin at the same time?

Yes. It runs three channels together, each at 1080p, and saves them as separate files.

Does it replace my rearview mirror?

No. It straps over your existing mirror and shows the camera feed on its own screen.

Yes. Parking mode requires a Rexing hardwire kit, sold separately, to keep power to the unit while parked.

It adds a cabin camera and a rear camera, so you get three views instead of one, at the cost of lower resolution per channel.

The cabin camera is fixed in the mirror housing, so aim the mirror itself to frame the interior.

The mirror unit, front and rear cameras with cabling, a car charger, and mounting hardware.
